Increased range on older models from big update?

[Scandinavian]

Try these comparisons in the Winter (assuming Northern hemisphere) to see material differences in range.

Why do you think this will be the case?

Would the car heat the battery and cabin much slower in Range mode in winter? So quite important to have the car preheated before leaving by having it plugged in?

I have not used the car in real winter condition and thus never experienced this. Temperatures down to 10 C is the lowest I have us3d the car in.

Actually, I was driving mostly in Range during winter times… and as I said, my average consumption was higher than at spring/summer.
my conclusion was, that outside temperatures over 20, makes lower consumption.
tyres and range mode do not play some serious role.
since early April, I’m mostly driving in Normal mode (eco ac, lowest chasis, 21” tyres), and my avg.consumption is still going down…

Much more energy is used - cabin heating for one rather than summer cooling. The HV heater eats energy. Range mode curtails this to either Eco or Eco Plus but then it becomes impractical. Screen demisting requires heat also.

Preheating won't do much for range either.

I've had 2 winters now < 5C (and below zero) and range drops to 220 miles from a summer high of around 240 miles. This drops further once the heater is on.

Expect 10 - 15 miles additional range at most during winter with Range mode active.

Thanks, I am with you. The cold will certainly draw much more energy.

I actually have found that preheating in the mornings have been beneficial to me, but it was not so cold. Once at a hotel charging over night and just below freezing point, the battery was heated yo 18 degrees before leaving. That saved me from having to slow down below legal speeds on motorway, in order to reach an Ionity station!

And some more details. The current in the battery is generated by an electrochemical reaction that is temperature dependent. Cold temperatures slow down the reaction so the amount of current is reduced, maybe to the point of not enough current to power the car if the temp is low enough. If the car is plugged in, it will use power from the mains to heat the battery. If the car is not plugged in, it will use some of its stored energy to heat the battery which reduces range. And as the battery has quite a bit of mass somewhere around 630kg/1400 lbs for the PB+ the amount of stored energy required is not trivial. Offsetting this is that Lithium Ion batteries can operate pretty efficiently down to around 10C. Below that the batteries start to become sluggish They also need some heat in them to be able to charge efficiently and the upcoming software upgrade appears to improve on that.

Search the forum as someone has been in -30C last winter - car still functioned.

Yes Frozen Robert. But he's not going very far. Plug it in when it's cold. Not rocket science. And then spend time learning how batteries work.

the car will still function but the range can take a big hit. I ran my tesla at temps of -20c and it ran just fine even after spending the night outdoors but plugged into a 110 outlet

to your point, the first time I encountered cold weather I parked my tesla with about 42 miles of range, ambient temps were about 15F overnight and I awakened to a car with about 18 miles of range and the supercharger was 24+ miles away. fortunately I am an early riser and at 5 am the highway wasn't very busy so I could nurse the car along under 40mph. this is what it reported about a mile from the charger, I did make it to the charger.

The german autobild car news estimates 50 extra km range (31 miles) with the software update. They don't provide a reference for these claims though....

Software-Update für alle Taycan-Modelle
Seit 2019 hat Porsche weltweit nicht nur mehr als 75.000 Taycan verkauft, sondern auch ständig dazugelernt. Nach mehreren kleineren Überarbeitungen erhält das Elektro-Flaggschiff jetzt ein umfangreiches Software-Update. Der Clou: Davon profitieren nicht nur Neukunden, das Software-Update ist für alle Taycan-Modelle erhältlich – völlig unabhängig von Alter, Laufleistung und Modellvariante. Vor allem die Taycan-Exemplare aus den frühen Baujahren profitieren von dem Update, da es die Fahrzeuge auf den Software-Stand des 2023er-Modelljahres bringt.
Bis zu 50 Kilometer mehr Reichweite

Zu den wichtigsten Neuerungen gehört auch eine Effizienz-Steigerung für die Allradmodelle. Hierbei wird in den Fahrmodi "Normal" und "Range" der Elektromotor an der Vorderachse quasi abgekoppelt (eine Software-Lösung, die von den GTS-Modellen bekannt ist). Es handelt sich dabei nicht um eine mechanische, sondern um eine elektronische Abkopplung. Zusammen mit einer verbesserten Konditionierung der Batterie – beispielsweise bei niedrigen Temperaturen – soll die Reichweite je nach Modell um bis bis zu 50 Kilometer (nach WLTP) steigen.

This list IS great. I have 2022 so some updates already in.

InnoDrive now available in Lithuania (small) and Vatican (really?) but still not in China!

I didn't think that private/secular autos could access the vatican

I received the update on my 2020 Taycan 4S this week, and will be taking a short road-trip of ~300mi (480km) over the Labor Day weekend in two weeks. That should give some meaningful evidence if the actual range is noticeably improved. I'll report back.

 

[raharris]

I agree. On long journeys I have only seen a 2 to 3 % increase in range. So about 10 to 12 km extra. Not worth the disadvantage of max speed at 140 km/h. Normal legal motorway speed here is 130 km/h.
Normal or sport mode for me with AC set at Eco unless the car is too hot.

You can set your own max speed in range mode….

Yes, but not over 140km/h.
